* - Remove UMAP filesystem. It was disconnected from build three years ago,Rong-En Fan2007-06-251-409/+0
| | | | | | | | | | and it is seriously broken. Discussed on: freebsd-arch@ Approved by: re (mux) Notes: svn path=/head/; revision=171023
* Make insmntque() externally visibile and allow it to fail (e.g. duringTor Egge2007-03-131-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | late stages of unmount). On failure, the vnode is recycled. Add insmntque1(), to allow for file system specific cleanup when recycling vnode on failure. Change getnewvnode() to no longer call insmntque(). Previously, embryonic vnodes were put onto the list of vnode belonging to a file system, which is unsafe for a file system marked MPSAFE. Change vfs_hash_insert() to no longer lock the vnode. The caller now has that responsibility. Change most file systems to lock the vnode and call insmntque() or insmntque1() after a new vnode has been sufficiently setup. Handle failed insmntque*() calls by propagating errors to callers, possibly after some file system specific cleanup.

| | | | | | | | | | | | | | | v_tag is now const char * and should only be used for debugging. Additionally: 1. All users of VT_NTS now check vfsconf->vf_type VFCF_NETWORK 2. The user of VT_PROCFS now checks for the new flag VV_PROCDEP, which is propagated by pseudofs to all child vnodes if the fs sets PFS_PROCDEP.
